The postseason is within reach for several teams in the Rockies’ organization.

With the minor-league season winding down next week, only the Modesto Nuts of the high Single-A California League are out of playoff contention. The Nuts have won only 40 games and are in danger of having their worst record since 1945.

Otherwise, postseason excitement is very much alive.

Tulsa of the Double-A Texas League has clinched a playoff spot behind the pitching of Jon Gray, Tyler Anderson and Eddie Butler.

Asheville of the low Single-A South Atlantic League, led by pitching stalwarts Antonio Senzatela and Johendi Jiminian and hitting stars Raimel Tapia, Correlle Prime and Ryan McMahon, have won the second half of the season in the South Division and clinched a spot in the SAL playoffs.

The Grand Junction Rockies are zeroing in on the South Division’s second-half title in the Pioneer League. The Western Slope Rockies go into the weekend with a five-game lead with a dozen games to go.

Tri-City of the Northwest League has a tougher path, needing to protect a half-game lead with 10 games remaining.

“With the potential of having four teams in the postseason, (that) isn’t bad,” said Zach Wilson of the Rockies’ player development department. “We have a lot of players we’d like to see perform in the postseason. There are a number of pitchers among them.”

The success in Tulsa could delay or even eliminate chances for Rockies fans to see Gray, the Rockies’ first-round draft pick in 2013, in September when major-league roster limits are extended. Gray already has pitched 124 ⅓ innings.

Anderson, the left-handed first-round pick in 2011, has had a stronger finish. Gray hasn’t recorded a victory since July 16 and is stuck on 10 wins. Anderson has won three of his past four decisions and is 6-4.

Asheville is loaded for its post-season bid.

Tapia leads the farm system hitters at .335. Prime and McMahon have a combined 90 doubles, a league record for two players on the same team.
